MAME HLSL Scanline adjustments for NOOBS (MAME Emulator preferably / Retroarch secondary)

[Go Fast]

Launch Box/ Big Box 12.12

Windows 10 Home edition

MAME ROM SET: 0.239

Using LB auto MAME rom set installer.

I’ve been trying to adjust the mame HLSL / Scanline & Curvature aspect so my flatlines gets more retro ‘esq within the bezel project. These references explain it but I can't get it to work with auto mame install to use scanline files. But whenever I use the LB mame rom set importer. Then I launch MAME, got into the ini adjust per these videos. I’ve seen no change in my mame settings. Is there anyway you can incorporate these adjustments with your awesome front end. Possibly even same integration in retroarch?

I’ve opened the ini in mame folder after import. Followed their settings exactly and no changes in Curve/ shading/ scanlines. Please HELP!!

If you manually edit the .ini file with the setting you are changing in the sliders does it load them correctly from within LB? It seems the issue is when in game and adjusting the sliders the .ini files is not actually getting updated.

Test by going into a game and making a change to one of the slider items. Then exit the game and open the Mame.ini file and see if it saves the change. I suspect it is will not.

I can’t even adjust the sliders in game. Nothing Changes. it still looks like distorted graphics. Im on a Dell XPS 8700 3rd gen I7 , 16 gb RAM 1050TI 4gb GPU.. I’m having no luck at all changing this.

If you launch a game directly in Mame (not using LaunchBox) can you move the sliders and it make changes on the screen?

I just tested 2 builds and there are no issues with these adjustments. I was able to tweak all the settings referenced in your links. LB should not ever affect how an emulator functions directly. LB simply sends command lines for the emulator to run the game selected.

1. Launch a game directly in MAME
2. its the tab key to adjust sliders? Make an minimal tweak save and back out?
3. go locate the mame ini with the preferred settings from there?
4. you simply just deleted out the existing and pasted in the tweak recommendations?
5. Save ini.
6. relaunch MAME and all is well?
7. or what am i missing with making these adjustments? Thank you for the help in advance

I got the settings to work. I tried this on version 12.1 it was a few back and no matter what i tried it did not enable said changes. Ive got it working now. Thank you for the speedy response. Still think it would be epic as a drop changes script edit the ini update. But might more involved then i think to automate it. I believe I’m in business. I was not running bezel project on the previous attempt
